ductus biliverus

This image shows a large ductus biliverus (BD) and one of its tributaries (Br D). A large artery (Art) is present for comparison. The smaller ductus biliverus is lined with simple cuboidal to columnar epithelium; the larger duct is big enough that the epithelium is beginning to stratify, and a stratified columnar epithelium can frequently be seen in ducts that size and larger. There’s an extensive supporting investment of CT around both of the ducts.The ductus biliverus system in the liver is set up pretty much like any other exocrine gland’s would be, and if you wanted to classify it structurally, it would be a compound form. Most species have two main ducts that carry the bile produced out of the substance of the liver, and convey it to the intestine (or possibly the gall bladder, in those animals that have one). These two ductus biliverus are joined together at some point out of the plane of this section, and the smaller one is a tributary of the larger
